“…Bacterial cellulose (BC) consists of long chains of β-Dglucopyranose units linked together by β1-4 glycosidic bonds, which result in the presence of a free hydroxyl group at the surface area. 20,29,[35][36][37] The degree of BC polymerization typically ranges from 2000 to 6000, while vegetal cellulose has a higher degree of polymerization, ranging from 13,000 to 14,000. 20,38,39 Although both BC and vegetal cellulose share the same molecular formula (C 6 H 10 O 5 ) n , they exhibit significant differences in their physiochemical properties.…”

“…BC displays a higher crystalline index, greater water-absorbing capacity, and higher purity. 20,37,[39][40][41][42] Cellulose has also demonstrated an isoelectric point lower than 2.8, resulting in a generally negative charge. 43 A positive charge can be induced in BC through the cross-linking of glycidyl trimethylammonium chloride (GTMAC), while the negative charge can be enhanced by oxidizing BC with 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO).…”

This review article provides a comprehensive overview of bacterial cellulose (BC), focusing on its physicochemical properties, production methods, purification techniques, and applications. It aims at providing a nuanced understanding of the current state of knowledge in those fields and bridging the gap between academic research and industrial applications. The physicochemical properties of BC, including its chemical structure, morphology, thermal properties, mechanical properties (such as tensile and compression properties), specific surface area, cytotoxicity, and biocompatibility, are discussed. Production methods of BC, including microorganism comparison, culture conditions, and vessel types, are thoroughly explored. Purification methods and sterilization techniques for BC are also addressed. Furthermore, the review highlights industries and applications that have shown interest in BC along with commercially available products, including medical, cosmetic, textile, food ingredients, and scaffolds in cell culture. A conclusion summarizes key findings and potential future directions in BC research and development.

However, due to LFM nanofibers growing in dense, stacked sheets: the LFM experiences a more selective nominal pore size of 30 nm compared to the 50 nm of MCE membranes .

Living Filtration Membranes Demonstrate Antibiofouling Properties

et al. 2021

Membrane filters are excellent prospects for increasing global access to safe water; however, they are significantly limited by fouling, particularly biofouling. Fouling plagues membranes by reducing efficiency and increasing maintenance and costs. Biofouling is particularly problematic due to the self-replicating nature of microorganisms and the secretion of extracellular polymeric substances that make the biofilm difficult to remove. Living filtration membranes (LFMs) are a sustainable membrane technology composed of bacterial cellulose and native microorganisms. In this study, natural water from Butte, Montana's three municipal drinking water sources (Basin Creek Reservoir, Moulton Reservoir, and Big Hole River) was pretreated with a coagulant and used in 400 min bench-scale dead-end filtration tests. Two membranes were comparedan LFM and a commercial mixed cellulose ester (MCE) membrane with a similar nominal pore size. Although the MCE membrane was more hydrophilic and had a smoother surface, surface properties that, in general, may improve fouling resistance for certain particles, a more rapid flux decline and live biomass were observed with the MCE membrane for all three waters. We suggest that the LFM's resistance to biofouling may be due to the proliferation of native bacteria, Acetobacter, which produces acetic acid, a known antibiofilm and antibacterial agent.

“…24,25 Therefore, one important and challenging aspect of the bacterial biosynthesis of NPs is identifying a costeffective culture medium. To reduce the cost of NP biosynthesis, many researchers suggest the use of low-cost culture media, that is, agro-industrial wastes, food wastes, or even sludges, 24 such as soybean straw, corncobs, olive mill waste, cottonstack, wheat straw, rice straw, pomegranate peel, and Colocasia peel; 26 feather and coconut oil cake; 27 and bacterial biomass grown in anaerobic fluidized bed reactors. 28 Another strategy is using residual bacterial biomass from already established fermentation processes.…”
